Soil contamination with diesel oil is quite common duringprocesses of transport and storage. Bioremediation is considereda safe, economical, and environmentally friendly approachfor contaminated soil treatment. In this context, studiesusing hydrocarbon bioremediation have focused on totalpetroleum hydrocarbon (TPH) analysis to assess process effectiveness,while ecotoxicity has been neglected. Thus, thisstudy aimed to select a microbial consortium capable of detoxifyingdiesel oil and apply this consortium to the bioremediationof soil contaminated with this environmental pollutantthrough different bioremediation approaches. Gas chromatography(GC-FID) was used to analyze diesel oil degradation,while ecotoxicological bioassays with the bioindicatorsArtemia sp., Aliivibrio fischeri (Microtox), and Cucumissativus were used to assess detoxification. After 90 days ofbioremediation, we found that the biostimulation and biostimulation/bioaugmentation approaches showed higher ratesof diesel oil degradation in relation to natural attenuation(41.9 and 26.7%, respectively). Phytotoxicity increased in thebiostimulation and biostimulation/bioaugmentation treatmentsduring the degradation process, whereas in the Microtoxtest, the toxicity was the same in these treatments as thatin the natural attenuation treatment. In both the phytotoxicityand Microtox tests, bioaugmentation treatment showed lowertoxicity. However, compared with natural attenuation, thisapproach did not show satisfactory hydrocarbon degradation. Based on the microcosm experiments results, we concludethat a broader analysis of the success of bioremediation requiresthe performance of toxicity bioassays.
